KEF’s new LS50W Active Music System contains an on-board Digital Signal Processor (DSP) that has been specially designed and implemented to give the listener the magical experience of articulate, spacious and pristine musical reproduction regardless of listening environment. We have combined the renowned performance of the passive LS50 with a DSP and amplifier set that perfectly matches the requirements of our drivers and enclosure design – all in an enclosure set that is barely larger than the passive original.
